LEANDER PELTON, OF DES MOINES, IOWA.

BROOM-SEWING MACHINE.

Application filed December 4, 1911.

To all whom 2'25 may concern:

Be it known that I, LEANDER PELTON, a citizen of the United States, residing at Des Moines, in the county of Polk and Stateof Iowa, have invented a certain new and useful Broom-Sewing Machine, of which the following is a specification.

In the art of broom sewing it has been customary heretofore to provide a broom clamp in which a broom may be supported and automatically moved past the point where reciprocating needles, perform the sewing. Before moving the broom clamp to position where the needles engage the broom it is necessary for the operator to wrap the thread around the bro m and also to readjust the broom within the clamp; then when this has been done the broom clamp is moved to position in the path of the needles and the operator must waituntil the broom has passed beyond the needles before he. can

apply another thread and, readjust the brorm in the clamp. V

The object of my present invention is to provide simple, durable and inexpensive means whereby an operator may cause the machine to sew a greatly increasednumber of brooms in a given period.' I r i More specifically it is my'object to provide a single broom sewing mechanism and a number of broom clamping devices so arranged that during the time that' one of the broom clamping devices is passing through between the needles the other is in position where an operator may place a broom in it and pass the thread around the broom so thatthere is always one broom clamp in position where the operator may prepare a broom to pass between the needles and another broom clamp in position between the needles so that the entire timeof an operator may be occupied and no time need be lost by the operator in waiting for the needles to perform their function.

More specifically it is my object to provide means whereby the broom clamps'are automatically returned to position-accessible to the operator after they have passed between the needles; and also to provide means for automatically bringing the broom clamps to position for moving between the needles.

A further object is to provide means for automatically closing and holding the broom clamping jaws duringthe time that Specification of Letters Patent.

they are needles. My invention consists in the construction, arrangement and combination of the various parts of the device, whereby theiobjects contemplated'are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which: I

Figure 1 shows a front elevation of a broom sewing'machin'e' embodying my invention with brooms in the'broom clamps. ig. 2 shows a side elevation of same." Fig. 3 shows a top'orplan View of same, and Fig. 4 shows an enlarged, detail, sectional view ofportions of the broom clamping jaws and the vertical adjustable broom holder within the jaws.

Referring 'to the accompanying drawings, reference I numeral 10 to indicate the machine frameprovided with a main power shaft 11 that may be driven bly afpulley 12' thereon. Mounted on top of t e which isprovided with a downwardly ex tended needle frame 14 at its lower end. I have provided for rocking the shafts 13 and thus reciprocating the passing through between the rame are two rockshafts 13, each of having (a needle 15 needles by means of crank arms '16 in the shaft 11, each of which crank arms is connected' by means of a'rcdl'? with an arm 18 onthe shaft 13. 'Thisneedle operating mechanism of itself forms no part of vmy present invention. Arrangednear thebottom of the frame 10 is a stationary shaft '19 having-two collars 20 ro-tatably mounted thereon. f On each of isa broom clamping standard 21 pivotally 7 parallel with the shaft 19 so that each of said standards 21 is, capable of universal movement relative to the stationaryshaft 19. At the upper end of the standard21 is a stationary clamping member 22 and supported to swlng in a plane front of the standard,

I a pivot} ed clamplng member. 23. Arranged within; 7

adjacent to the end of said lever, is a notched arm 27 yieldingly held by a spring 28 to position in engagement'with the lever 26.. so

' per end a ratchetwheel 35.

that the lever may be yieldingly held by the arm 27 in any one of the notches on said arm in which the lever may be placed. By this means the broom holder may be vertically adjusted within the broom. clamp when the sides of the broom clamp are not firmly held together. The particular construction of the broom holder and its adjusting means is not important and any of the ordinary forms of this device may be used.

To provide for automatically clamping a broom between the clamping jaws and for advancing the broom clamp through between the needles, I have provided the following mechanism: Arranged on one side of the broom clamp, I have provided two rollers 29 designed to engage one of the clamping jaws when said jaw passes between the needles. On the opposite jaw, I have provided on its outer face a rack 30 designed to be engaged by two pinions 31 and 32, which pinions are both in mesh with an intermediate idler pinion 33 which causes both of the pinions 31'and 32 to turn in the same direction. To provide means for moving said pinions, I have mounted the pinion 32 on an upright shaft 34 having at its up- This ratchet wheel is driven by means of a cam 36 on the power shaft 11, which cam is arranged to engage an arm 37 fixed to an upright rock shaft 38. This rock shaft has at its upper end an arm 39 having a link &0 pivoted to it and said link in turn is pivoted to an arm 41, which arm isv rotatably mounted on the upright shaft 34 and is provided with a pawl 4-2 designed to engage the ratchet wheel 35. A pawl 43 is also mounted on the frame of the machine to engage'the ratchet wheel 35 to prevent backward movement thereof. By this means, it is obvious that the broom clamps will be moved through between the needles at a speed proportionate to the speed at which the needles are moved and the said pinions 31 and 32 are so spaced relative to the rollers 29 that when a broom clamp passesbetween the pinions onone side and the rollers on the other the jaws thereofwill be firmly held together to grasp the broom. I preferably provide a curved portion 30 on the inner end of the rack 30 that will first enga e thepinion 31 and move the jaws together.

In orderto provide for returning the broom clamps to starting position after they.

have passed between the needles, I employ .the following: Immediately in the rear of the positionrthata broom clamp occupies after passing through between the needles is a forwardly extended track member d4. This track member has two inclined faces, one. extending rearwardly and toward the left and the other rearwardly. and toward the right, each of which is connected to a substantially semicircular track member 1 45,

which track members both incline downwardly and to the front of the 'machine. One of the broom clamps is intended after passing between the needles to move first to the left and then forwardly, and in order to accomplish this purpose the standards 21;

are each provided with an offset portion at 46, as shown in Fig. 1, one offset portion being inclined to the right and the other to the left. Hence when that particular broom clamp, shown at the center of Fig. 1, passes between the needles the standard 21 will en-- as soon as they have passed beyond the point where the pinion 32 engages the rack 30. For the purpose of automatically engagmg each broom clamp when at its forwardly inclined position and moving it toward the pinions 31, I have fixedto the stationary member of each broom clamp ahooked arm 47 projected forwardly from the. broom clamp and of such size and shape that the hooked arm on one broomfclamp will pass forwardly around the other broom clamp when the latter is inits forwardly inclined position and then as the first mentioned broom clamp moves between the needles the second will be movedby said hooked arm to position for entering between the needles.

In practical operation and assuming that the parts are in the positions shown in Fig. 2, and that the machine is beingoperated, thenthe broom that is in position adjacent to the needles will be firmly clamped and will be advanced between the needles auto matic'allv. During thistime the other or forwardly inclined broom clamp will have its jaws relaxed so that the operator may readjust the broom holder between said jaws and the operator will also have an opportunity to place the broom so that as soon as the first-broom has been sewed the second'broom will be in proper condition to enter between the nee-,-

thread around the Y sarily idle during thetimethat the operator.

is manipulating the broom within the clamp and placing a thread around it. By means of my lmprovement the sewing operation may be substantially continuous for the reason that by having two clamps one of them may be moving through between the needles while the operator is readjusting and placing the thread'around the other so that both the operator and the machine may be substantially continuously employed.

By providing a series of broom clamps that are capable of being movedcontinuously in one direction past the needle-operating mechanism and by having these broom clamps capable of independent movement toward and from each other, I accomplish a very desirable result in that while the neeles-are engaged in the operation of sewing the broom that is in one of the clamps and is necessarily advancing slowly, the other clamp may return rapidly to position accessible to the operator and the operator may then pass a twine around a broom in said latter clamp, clamp may be moved to position adjacent to the former and before the operation of sewing is completed on the broom in the first clamp, so that, when the broom in the first clamp is completely sewed the needle operating mechanism will at once engage the broom in the second clamp without loss of time and without stopping the broom sewing mechanism o that the broom sewingimechanism may operate continuously and the operator may put in his time continuously in applying twine to the-various broomsand in readjusting them within the clamps. Obviously if a series of broom clamps are provided that are spaced apart from each other and not capable of movement toward each other, then a great deal of time is wasted during the time that the needles cease operation on one broom and before-they begin operation on the next, and if, on the other hand, a series of broom clamps are provided in which the brooms are not properlyspaced apart at any time then the operator could not conveniently and easily apply the twine to one of the brooms ing operated upon by the needles.

The rollers that engage the sides of the,

broom clamp may either be smooth or toothed as desired and in the accompanying claimswhere the term rollers isemployed in describing these elements, I intend the term to cover either smooth or toothed rollers. q

In order to successfully accomplish the purposes for whichmy improved sewing machine is intended, it is essential that the broom clamps be mechanism at a relatively slow speed, and that they then be returnedto the starting point at a relatively fast speed so that only a-few broom clamps needbe employed and I to position and then the latter broom the operative points of the needle means for rapidly while the other was be-' advanced past the sewing.

the operationof sewing may be carried onmeans for slowly moving a broom clamp through a path of travel in operative relationship to the needle operating'mechanism, and means for rapidly returning a broom clamp through a different path to position for reentering operative relationship-to the needle operating mechanism.
